Hi. On Sunday I woke up and I had a red spot that sorta looked like a blister, above my right breast , but higher up on my chest, and it was itching. As the day went by, I got more on my rt. shoulder and some down on my back. Then another showed up on my left breast. It itches really bad, it fills like it burns a little, and it is sore also. Its more sore on my rt. shoulder than anywhere. Would you have any ideal what this might be? I don t take any new medicines, folic acid, asprin, tropel xl, hct. This all That I take. I ve been painting my bathroom with a paint that has primer and paint together, but I ve used this before. I am 63 years of age, female, and weight 230. It doesn t look a rash just blisters & red, & itches & sore. My name is Patsy. Thank you.
